三、新环境准备及检查

配置新RAC环境，RAC安装在本次文档中不再做详细说明。

查看hosts文件

[root@soul01 db_1]# cat /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 localhost

192.168.8.141 soul01

192.168.8.142 soul02

192.168.8.143 soul01-vip

192.168.8.144 soul02-vip

10.0.0.141 soul01-priv

10.0.0.142 soul02-priv

确认数据库版本及用户信息、配置oracle环境变量

[oracle@soul01 ~]$ sqlplus /nolog

SQL*Plus: Release 10.2.0.5.0 - Production on Wed Dec 4 05:33:17 2013

SQL> exit

[oracle@soul01 ~]$ id

uid=1001(oracle) gid=501(oinstall) groups=501(oinstall),502(dba)

[oracle@soul01 ~]$ cat ~/.bash_profile

# .bash_profile

# Get the aliases and functions

if [ -f ~/.bashrc ]; then

. ~/.bashrc

fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH

export ORACLE_BASE=/oracle

export ORACLE_HOME=$ORACLE_BASE/db_1

export CRS_HOME=$ORACLE_BASE/crs_1

export ORACLE_SID=xysoul1

export PATH=$ORACLE_HOME/bin:.:$CRS_HOME/bin:.:$PATH

[oracle@soul01 ~]$

再次通过xpinfo工具查看磁盘信息（由于此次模拟环境为虚拟机，下面LDev号为模仿）

Device File	CU:LDev
/dev/sdc5	01:b2
/dev/sdc6	01:b3
/dev/sdc7	02:46
/dev/sdc8	02:a4
/dev/sdc9	02:a5
/dev/sdc10	02:a6

编辑文件60-raw.rules，添加如下内容

#ORC

ACTION=="add",KERNEL=="sdc5",RUN+="/bin/raw /dev/raw/raw11 %N"

#Vote disk

ACTION=="add",KERNEL=="sdc6",RUN+="/bin/raw /dev/raw/raw21 %N"

#ASM SPFILE

ACTION=="add",KERNEL=="sdc7",RUN+="/bin/raw /dev/raw/raw3 %N"

#DATA ASM DISK

ACTION=="add",KERNEL=="sdc8",RUN+="/bin/raw /dev/raw/raw4 %N"

ACTION=="add",KERNEL=="sdc9",RUN+="/bin/raw /dev/raw/raw5 %N"

ACTION=="add",KERNEL=="sdc10",RUN+="/bin/raw /dev/raw/raw6 %N"

KERNEL=="raw11", OWNER="root", GROUP="oinstall", MODE="640"

KERNEL=="raw21", OWNER="oracle", GROUP="oinstall", MODE="644"

KERNEL=="raw[3-6]", OWNER="oracle", GROUP="oinstall", MODE="660"

执行命令：start_udev

两边对裸设备进行检查：

[root@soul02 /]# raw –qa

/dev/raw/raw1: bound to major 8, minor 21

/dev/raw/raw2: bound to major 8, minor 22

/dev/raw/raw3: bound to major 8, minor 39

/dev/raw/raw4: bound to major 8, minor 40

/dev/raw/raw5: bound to major 8, minor 41

/dev/raw/raw6: bound to major 8, minor 42

/dev/raw/raw11: bound to major 8, minor 37

/dev/raw/raw21: bound to major 8, minor 38

[root@soul02 /]# ls -l /dev/raw/*

crw-r----- 1 root oinstall 162, 1 Dec 4 05:04 /dev/raw/raw1

crw-rw---- 1 oracle oinstall 162, 5 Dec 4 05:39 /dev/raw/raw5

crw-rw---- 1 oracle oinstall 162, 6 Dec 4 05:39 /dev/raw/raw6

查看目前集群服务

[oracle@soul01 dbs]$ crs_stat -t
